Freeware INS here.

In know this has been posted before but believe it or not there are still simmers who haven't discoverd it.  A very realistic and valuable add-on especially if used in older pre-1980 airliners.  Adds payware realism to freeware aircraft.  Go here  http://www.simufly.com/ins/

99.9% realized, failure codes modeling, triple mixing in 3 CDU installations, DME updating, pre-configured panel.cfg's for some aircraft, nicely done installation instructions and a freindly helpful forum there.

Thanks, Gary,

I've been using FS since 2000 and I have never heard of this.

And I love the anti-piracy warning.

Nice, gotta put that russian one in my Tupolevs.  :)

I'd be interested in checking out the russian box if I can find it on that page.  Lordy Lordy.  I can help myself okay in spanish, german, and even french.  They use our letters at least.  Russian on the other hand
